The guidance in AIM 1-2-3(d) was updated a while back. If your non-WAAS GPS has fault detection and exclusion capability, and you perform a pre-flight RAIM check, then you may file based on a GPS-based IAP at either your destination or your alternate, but not both. If the above conditions can't...

It was actually defined in the second sentence of AIM 5-4-5k quoted above. Here's a picture if that will help.

There's more in AIM 5-4-5k: k. Vertical Descent Angle (VDA) on Nonprecision Approaches. FAA policy is to publish VDAs on all nonprecision approaches. Published along with VDA is the threshold crossing height (TCH) that was used to compute the angle. The descent angle may be computed from...

Perhaps I was cavalier in my use of the term destination. I guess it depends on the interpretation of destination vis a vis the first airport of intended landing. I have not yet found any published interpretations for those particular phrases relative to each other. I acknowledge up front that...

Total agreement with this point and the subsequent advice. While most pilots consider alternate planning to be only a pre-flight exercise, 14 CFR 91.167 "Fuel requirements for flight in IFR conditions" applies at all times you are operating in IFR conditions (not just pre-flight planning)...

I received a report recently that the KCRQ RNAV (GPS) X RWY 24 approach is indeed in the Garmin G1000 database. However, the OCN transition (the one with the RF leg) is not available, only the VECTORS transition. This creates a potential point of confusion. Some pilots have been using the...

I'd be curious what the probe reads when surrounded by a bag of ice water (50% ice, 50% water) after waiting for temps to stabilize--poor man's probe calibration. The temperature of that bag should be right around 0dC (melting point of the ice in the bag).
